My invention relates to refrigerating apparatus and is designed particularly for use on an automobile equipped with a cooling devicecomprising a radiator through which a cooling uid is designed to be circulated and having means for causing a stream of air to flow through the radiator so as to be cooled thereby. It is the `object of my invention to provide an improved unit form of apparatus for cooling a supply of water and forcing it through a cooling radiator, such unit being .arranged so as to be suitable for effective use at any point on a motor vehicle where room can be found for mounting it.

In working out mv improved arrangement, it has been one of my objects toprovide a mechanism which shall be effective in operation, which may be produced at low cost by the use of parts. capable of being easily produced and assembled, which shall be so simple in construction and arrangement as to enable anyone with very little mechanical skill or knowledge to operate it successfully, which may be easily and quickly mounted in operative condition upon a motor car, and which shall be effectively operative by the use of materials readily available to motorists without the necessity for a search therefor. To this end, I have employed for my apparatus an improved insulated tank arranged to have a suitable supply of ice supplied thereto; a pump for taking water from the tank and forcing it to the desired point of use and then returning it to the tank for renewed cooling; and a motor for operating the pump, the pump and motor being of such size and arrangement as to be instrumental for producing an effective fiow of water through the tank while at the same time being capable of being operated with a low expenditure of electric current so as not to drain the car battery, the parts being so arranged and so related as to operate with high eiliciency for'the attainment of my objects. U

It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which' I have accomplished my several objects are illustrated in the accompanying drawings, in which Fig. 1 is a vertical sectional view throughgthe preferred form of my improved apparatus, beingv taken substantially at line I-f-| 'of Fig.- 2. l

Fig. 2 is a horizontal sectional view taken at the line 2-2 of Fig. l. n

Fig. 3 is a vertical sectional view taken at the line 3-3 of Fig. 1.` v

Fig. 4 is a vertical sectional view taken on a considerably enlarged scale at line of ljg. 1,

Fig. 5 is a view showing the construction of the Water pump, substantially as seen at the line 5-5 of Fig. 4, and

Fig. 6 is an enlarged detail view of the upper left hand corner portion of the device'as shown 5 in Fig. l. Referring now to the several figures of the drawings, in which corresponding parts are indicated by the same reference characters, I0 indi- Cates a tank member preferably formed of sheet 1Q metal Wall sections separated by insulation material i I of any suitable type. The tank member I0 is closed at the top by means of a lid member i2 likewise formed of sheet metal wall sections separated by insulation material I l, the lid being 15 movably mounted in position by means of hinges |3401 any suitable type. In the arrangement shown a handle i4 is provided on the top face of the lid or cover member I2, and an ordinary trunk latch structure I5 is provided for holding gg the lid releasably in closed position. In the arrangement shown, a gasket i6 preferably formed of rubber is provided between the lid and f thev upper edge of the body I0 of the tank, such gasket being held in position by reason of its 25 undercut relation with respect to the bodyof the tank. The arrangement is such that a supply of ice within the tank is thoroughly insulated from the surrounding atmosphere so as to be preserved eiectively within the tank.

On the outer face of the tank, I have provided a heavy metal plate il in the form of a channel, such plate being secured in position across the bottom edge portion of one end of the tank by means of bolts i8, as is best shown in Fig. 2. 35 The heads of the 'bolts I8 are preferably covered with solder so as to prevent the leakage of water around the'bolts. In the arrangement shown, a gasket I9 is interposed between the plate I1 and the end of the tank. y o

On the outer face `of thel plate I 1, I have mounted an electric motor 20 which is held in position by means of a bracket 2| bent into the shape of a cradle for fitting the side of the motor.

In axial alignment with the vmotor 20 I have pro- 5 vided a pump 22 supported inposltiongby means ofa bracket 23. As is best shown in Fig. 4, the motor shaft 24 is connected with the shaft 28 of the pump by means of a wire coil 28 whichl surrounds the ends of the shafts andis secured 50 thereto by means of solder or in any'other suitable manner, the coil being wound in the direc- 'tion so as to cause it to contract upon the application ofpower from' the motor to the pump. The coil 26 constitutes in effect a universal joint con: 5s

means of a nozzle `member `22 opening into a housing member Il which isformed Vwith. the closure plate Il of the casing ofthe pump, the

the shafts with respect to each other.

As is best shown inFlgs. 4 and 5, my pump 22 comprises a hub portion 21 provided witha plurality of outwardly extending `vanes or paddles 2l adapted to be rotated by the shaft 2l within the pump chamber `29. The pump casing is pro-` vided at one side with an outlet nozzle leading `tangentially from the chamber and: having an outlet pipe 2| connected therewith. An inlet pipe 32 is connected with the pump chamber` by housing Il providinglan axialiextension of the pump chamber through which ,water entering' through the` inlet pipe 22 is` afforded access to the vanes 2l. The arrangement is` such that upon rotation of the pump in counterclockwise direction in Fig. 5 fluid is forced out through the pipe Il so as to establish a suctionnenect within the chamber 2! for causing water or other iiuid to be drawn in through the pipe 32.

For protecting the motor 2l and `thepump 22 and their connections, I have 'provided a shield Il ,which in the arrangement shown is formed of sheet metal secured to the flanges of the channel plate i1.. As is clearly shown in Figs. 2 and 3,

both ends ofthe shield Il are open so astoper-I mit an ample supply` of airto be `provided for cooling the motor 2|l.f` n v n As isrbest shown in Figs. 1 and2,the pipe I2 extends through the `wall of` the tank member Il so as to open within the tank near thebottom. Aboutthe open inner end of the Vpipe 32,`

I have provided` a strainer comprising a plate 21 bent into the shape of, a housing, being provided with a great number o! openings .through the plate and having a fine wire mesh Il `stretched i about'the housing so as to act as a strainerfor the water passing outthrough the pipe 82. By

the use of such astrainerhavingra comparatively very large screen surface, the icein 1Ithetank is kept from clogging up the end ofthe pipe; 22.

In one sidewall of the tank member Il, I have provided an inlet pipe extending. lengthwise along the wall of thetank land openinginto the tank in .spaced relation from the bottom. The

pipes l0 and 2l extendupwardly through thetop i wall of the shield. inthe `arrangement shown passing through `the top flange of theehannel bar l1 ratherthan through the shield member 3l. Such pipes are designed to be connected by any suitable means with' the` radiator of a cool--` inside metal lining ofthe tank y.for preventing.

leakage at these points.

In the, arrangement shown. the tank Il is mounted in position by means of clips Il which engage the plates 42 securedat opposite ends of` the tank on its bottom face, `asis clearly` shown in l'lig. 3. Y t.

l By the use of my improved` construction. I have provided a unit form of cooling device which is supplied ready for mounting upon a pleasure car supply of ice in the nection between the shafts so as to obviatethe necessity for `careful and accurate alignment of or a truck at any point where room isfound for the tank. .The shield ll provides ample protection for the workina parts so asto protect them from damage. 'Ihe motor and pump are of such size and arrangement as to be eiIective ior taking a substantial vamount of water from the tank l0 and returning it to the tank for renewed cooling after such .water passes through acooling radiator. 'I'he motor 201s preferably to be driven by current from the usual storage battery of the car or truck. y fIhe connections between the unit and the cooling radiator will ordinarily be effected bythe' use o! `rubber hose which are adapted `to be slipped easily into position `upon the ends of the pipes Si andll.:

While I preferto` employ the form and art rangementpi parts as shown in my drawings and as 'above described; it is to be understood that my invention is` not limited to the apparatus as shown except `so far as the claims may be so limited, it being understoodthat changes might well be made in theform and arrangement of parts without departing from my invention.`
